Objectives: To investigate the safety and cost-effectiveness of outpatient thyroidectomy and provide a systematic postoperative protocol for safe discharge., Methods: In this retrospective review, the medical records of all patients who underwent total, hemi, or completion thyroidectomy from July 2017 to April 2019 at 2 tertiary care hospitals were reviewed. Multivariable analysis was performed on the potential predictors of postoperative complications. Healthcare costs were calculated by the type of admission based on the average costs at the 2 centers., Results: One hundred twenty-two patients were enrolled in this study. The majority of cases were in the outpatient group (n=76, 62.3%). Total thyroidectomy was the most prevalent type of surgery (n=90, 73.7%). There were a total of 20 complications in 18 patients (inpatient=9 versus [vs.] outpatient=9). No cases of cervical hematoma or bilateral vocal cord paralysis were encountered. No significant difference was found between the type of admission (outpatient vs. inpatient) and postsurgical complications ( p =0.24). The multivariable regression model retained significance for male gender and American Society of Anesthesiologists Classification III as potential predictors of postoperative complications. Healthcare costs would be reduced by at least 15.5% with the implementation of outpatient surgery., Conclusion: Outpatient thyroidectomy is as safe as inpatient thyroidectomy given the proper selection of cases. We project cost containment of over $711 thousand per 1,000 cases for outpatient thyroid surgeries., (Copyright: © Saudi Medical Journal.)

Purpose: As the lack of consensus in the initial levothyroxine (LT4) dose titration following total thyroidectomy exists, the aim of this study was to identify and quantify predictive factors for LT4 dose replacement., Methods: A retrospective analysis of a prospectively gathered data of 234 patients who underwent total-thyroidectomy at two institutions between November 9, 2009 and January 1, 2016 was conducted. Outcome variable was the clinically observed optimal LT4 dose. Linear and polynomial regression methods were used for prediction. Continuous variables were tested for mean differences using Student's t-test and association using Pearson's correlation., Results: We identified Body Surface Area (BSA) as the most significant predictor. We propose a model that titrates LT4 dose based on BSA (1.4 µg /kg/day for BSA > 1.79 m 2 vs. 1.7 µg /kg/day for BSA ≤ 1.79 m 2 ; P = 0.00). Men required higher doses than women and no differences were noted based on DM status or pathological diagnosis., Conclusions: Our analysis shows BSA as an independent predictor of LT4 dose post total thyroidectomy. Despite the possibility of generating different equations for predicting LT4 post total-thyroidectomy, finding a practical and clinically relevant prediction model is yet of limited efficiency.

Background: Hypoparathyroidism is the most common complication after thyroidectomy and the main reason for frequent outpatient visits; however, there is a poor understanding of its outcomes and no clear follow-up strategies are available. We aimed to predict post-thyroidectomy hypoparathyroidism outcomes and identify relevant factors., Methods: A multicenter, standardized prospective study was conducted. The parathyroid hormone level (PTH) was measured preoperatively and at the first hour after surgery, then at each outpatient follow-up visit after 1 week, 3 weeks, and 1 month, and then every 2 months, until it either reached normal values or up to 6 months. Cox proportional hazard modeling was used to determine the factors that affect PTH recovery. A Weibull distribution model was used to predict time to recovery. Both models were evaluated by goodness of fit., Results: A total of 186 patients were enrolled in the study; 53 (28.5 %) developed hypoparathyroidism, 47 of them (88.6 %) females. Their mean age was 41.2 years, and 11.4 % were diabetic. Of these women, 33 (62.3 %) recovered within 1 month, 10 (18.9 %) recovered after 1 month but within 6 months, 7 (13.2 %) did not recover within 6 months, and 3 (5.6 %) missed follow-up. Factors that are found to affect and predict the speed of recovery were the preoperative PTH level, perioperative percent drop in PTH level, diabetes mellitus, and gender., Conclusions: This study provides potentially useful information for early prediction of PTH recovery, and it highlights the factors that affect the course of hypoparathyroidism recovery, which in turn should be reflected in better patient management, improved patient satisfaction, and overall cost-effectiveness.

Objective: To optimize and individualize post-thyroidectomy hypocalcemia management., Study Design: A multicenter prospective cohort study., Setting: Two tertiary care hospitals., Subjects and Methods: parathyroid hormone (PTH) was measured preoperatively, then at 1 and 6 hours after surgery. The required doses of calcium and vitamin D were defined as those maintaining the patients asymptomatic and their cCa ≥ 2 mmol/L. They were used as an endpoint in a generalized linear mixed effect model (GLIMMEX) aiming to identify the best predictors of these optimal required doses. Models were evaluated by goodness of fit and Receiver Operating Characteristic (ROC) curves., Results: One hundred and sixty-eight patients were analyzed; 85.1% were female, 49.3% had BMI > 30, and 64% had vitamin D deficiency. Post-thyroidectomy hypocalcemia was found in 25.6%, of whom 18 (41.9%) were symptomatic and received intravenous calcium. First hour percentage of drop in PTH correlated positively with the severity of hypocalcemia (P < .0001). The GLIMMIX prediction model for oral calcium requirement was based on first-hour percentage change from preoperative PTH level, preoperative actual PTH, BMI, and thyroid function. The same predictors were identified for vitamin D, except that thyroid function was replaced with vitamin D status. These factors were used to build predictive equations for calcium and vitamin D doses., Conclusion: Our findings help to optimize management of post-thyroidectomy hypocalcemia by assisting in the early identification of those who are not at risk of hypocalcaemia and by guiding early effective management of those at risk. This may reduce complications and medical cost., (© American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.)

Objective: The aim of this study was to evaluate the clinical value of preoperative thyroid autoantibodies with reference to the post‐thyroidectomy patient pathology. Design: A retrospective cohort study. Setting: Two tertiary care academic hospitals. Materials and Methods: A total of (n = 473) subjects who underwent thyroidectomy from 2009 to 2019 were included. Preoperative serum thyroid autoantibodies (anti‐thyroglobulin [anti‐Tg] and anti‐thyroperoxidase [anti‐TPO]) were measured, and the potential predictors of postoperative pathological diagnosis (age, gender, and thyroid autoantibodies) were assessed using multivariable regression models. Results: Patients with positive thyroid autoantibodies were more likely to have malignant disease than benign disease; adjusted odds ratio (AOR) = 1.6 (1.3–2.7, p = 0.002) for anti‐Tg, and AOR = 1.6 (1.1–2.5, p = 0.027) for anti‐TPO. A subset analysis of the same predictors performed on patients with cancer (malignant vs. microcarcinoma) showed that patients with ages ≥40 were more likely to develop microcarcinoma as opposed to malignant disease; AOR = 1.8 (1.1–3.1, p = 0.03) for anti‐TPO, and AOR = 1.7 (1.0–2.9, p = 0.04) for anti‐Tg. Conclusion: Preoperative thyroid autoantibodies could be used clinically to predict the risk of malignancy in thyroid nodules, thus helping guide treatment decisions in patients with thyroid nodules and speeding up the decision to undergo surgical intervention.
